VBB's explanation sounds fine to me.

Obviously it is limited to the in an out breath in Anapanasati. When a meditator is sitting cross-legged with back erect, obviously they cannot engage in any unwholesome bodily actions (such occurs in those kamma suttas where kaya sankhara is used to described bodily kamma).
SarathW wrote: ↑Mon Dec 03, 2018 8:07 pmWhat I am saying why did Buddha use the word "calming bodily fabrication" instead of "calming the in-out breath"? The calming bodily fabrications seems to have a wider meaning.
The kaya-sankhara is the breath - per MN 44. MN 117 refers to two sorts of dhamma: noble dhamma and puthujjana dhamma. MN 44 is noble dhamma.

Recollection of pubbe nivasa (past abodes) is after 4th jhana (unless it is Mahayana). Therefore, in prison, teach the prisoner the Buddha forgives them of their sins and to forget the past & not long for the future. Teach the prisoner
MN 131 (until they reach 4th jhana).

3rd & 4th step cannot be separated. There is rupa-kaya and nama-kaya. The breathing conditions (sankhara) both the rupa & nama kaya. For example, if the breathing is calm; the body & mind are calm. If the breathing is agitated; the body & mind are agitated. 3rd step is experiencing all kaya, i.e., experiencing how the breathing, body & mind interrelated with each other. It is in the 3rd step you understand what the term "kaya sankhara" means. Therefore, the 4th step cannot be understood without the 3rd step.

The kamma suttas using the term "kaya sankhara & mano sankhara" are not noble right view yet you seem to be giving the mundane (puthujjana) suttas preeminence over the supramundane (noble). MN 118 Anapanasati Sutta refers to a Noble Sangha. MN 118 Anapanasati Sutta is Noble Dhamma.

Calming the
bodily formation, I shall breathe in,’ thus he
trains himself; ‘calming the bodily formation, I
shall breathe out,
Isn't this sentence proves that in and out breath is not only the bodily formation?
No. The Buddha did not use the term "bodily formation". The Buddha did not speak in English. "Bodily formation" is only a translation. I think you need to read MN 44 to examine the meaning of the three sankhara (kaya, vaci & citta).
